The valve seat 41 has a main valve block 411, and a closed valve block 413 that defines a valve chamber 412 together with the main valve block 411. The main valve block 411 has a portion to the fixed seat 2 a transmission shaft portion 414 protruding from the through hole 21 and coupled with the power source 44, a first annular groove 415 disposed on the outer circumferential surface and corresponding to the first air guiding hole 324 of the air guiding seat 32, and a through hole a first annular groove 415 and a first valve hole 416 of the valve chamber 412, a second annular groove 417 disposed on the outer peripheral surface and communicating with the second air guiding hole 325 of the air guiding seat 32, and a second through hole The number of the first valve hole 416 and the second valve hole 418 of the annular groove 417 and the second valve hole 418 of the valve chamber 412 is not limited to the number disclosed in the embodiment, and may be several. The closed valve block 413 has a straight through hole 419 having a shoulder ring 410 at the lower edge of the first valve hole 416. The power source 44 has a shaft 441 for outputting power, and a shaft 442 for urging the shaft 441 and the transmission shaft portion 414 of the valve seat 41.

In the present embodiment, the jig 5 includes a mounting seat 51 fixedly mounted below the closing valve block 413 of the valve seat 41, and two clips pivotally mounted below the mounting base 51 by a pivot 52, respectively. Claw 53, this The number of the equal jaws 53 is not limited to the two disclosed in the embodiment, and may be three or four or the like. Each of the jaws 53 has a fulcrum portion 531 through which one of the pivot shafts 52 passes, a nip portion 532 spaced from the fulcrum portion 531, and a fulcrum portion 531 and the clamp a control portion 533 between the portions 532, the clamping portion 532 has a clamping pad 534 made of a soft material, and the clamping pads 534 of the clamping jaws 53 are oppositely disposed, and the control portion 533 has an elongated guiding channel. 535.

In the present embodiment, the opening and closing mechanism 6 includes a piston unit 61, a lifting plate 62 that is lifted and lowered with the piston unit 61, and two guide grooves 535 mounted on the lifting plate 62 and penetrating the jaws 53, respectively. Control pin 63 inside. The piston unit 61 has a piston rod 611 that passes through the shaft hole 419 of the valve seat 41 and is fixedly coupled to the lift plate 62, and a piston that is located in the valve chamber 412 and is coupled with the piston rod 611. 612, the piston 612 has a partition 613 that abuts against the inner wall surface of the valve chamber 412. The partition 613 of the piston 612 divides the valve chamber 412 into two and is movable between the first valve hole 416 and the second valve hole 418 of the valve seat 41.

In the non-clamping position of the clamp device of the present embodiment, the screw cap 12 of the container 1 is substantially located between the clamping pads 534 of the clamping jaw 53 and the The container body 11 is fixed. Since the container body 11 is not fixed in the present invention, it will not be described in detail. At this time, the top edge of the partition portion 613 of the piston 612 abuts against the shoulder ring 410 of the valve seat 41. Below.

Referring to Figures 1, 2, 4, when the clamp 5 is to be un-clamped by Figure 1 When the position is switched to a clamping position shown in FIG. 4, first, the gas enters the first ring groove 415 of the valve seat 41 from the first pipe member 326 via the first air guiding hole 324 of the air guiding seat 32, and then The piston unit 61 that pushes the opening and closing mechanism 6 from the first valve hole 416 into the valve chamber 412 moves downward. When the piston unit 61 moves down, the lifting plate 62 and the steering pins 63 are driven. Moving down together, the control pin 63 synchronously drives the clamping portion 532 of the clamping jaws 53 to swing in the direction of the screw cap 12, when the clamping pad 534 of the clamping jaws 53 firmly holds the screw cap 12 The clamp 5 is switched to the clamping position, at which time the bottom surface of the piston 612 of the piston unit 61 will abut against the top surface of the closed valve block 413 of the valve seat 41, and the partition of the piston 612 The bottom edge of the 613 is also slightly higher than the second valve bore 418 of the valve seat 41.

Referring to Figures 2, 4 and 5, when the jaws 53 of the clamp 5 securely hold the cap 12, the power source 44 will drive the valve seat 41 to rotate, since the clamp 5 is fixedly mounted to the valve The seat 41 of the seat 41 is closed below the valve block 413, so that the clamp 5 is also rotated to screw the screw cover 12 to the container body 11, and the assembly work is completed.

It is further illustrated that, in the process of screwing the cap 12 in the embodiment, although the valve chamber 41 of the valve seat 41 is filled with air, the valve seat 41 is abutted upward, but the valve is The thrust bearing 43 is interposed between the seat 41 and the guide rods 31. Therefore, the thrust bearing 43 can prevent the valve seat 41 from abutting against the rotation of the valve seat 41. Further, when the air pressure is excessively large and flows along the gap between the rotary passage 321 and the valve seat 41, excessive atmospheric pressure can be released from the pressure relief hole 320, in order to prevent deformation of the O-ring disposed above and below. On the other hand, when the rotation During the process of screwing the cover 12 into the container body 11, since the threads have a height, the clamp 5, the rotating mechanism 4, the screw cap 12 is gradually screwed into the container body 11. The guiding mechanism 3 and the opening and closing mechanism 6 also move downward together, and thus the elastic members 34 that compress the top support between the frame plate 33 and the fixing base 2 accumulate elastic force.

As shown in FIG. 5, when the cap 12 completes the assembly operation, gas will enter the valve chamber 412 of the valve seat 41 from the second tube member 327 to push the piston unit 61 up, which is originally located above the piston 612. The gas is discharged from the first tube member 326. During the upward movement of the piston unit 61, the jaws 53 that originally hold the screw cap 12 are gradually relaxed, and thus the pull-down force is released. At this time, the elastic members 34 release the elastic force, and the guiding mechanism 3, the rotating mechanism 4, the opening and closing mechanism 6 and the clamp 5 are topped together, and finally moved to the non-clamping shown in FIG. position.

It can be seen from the above description that the clamp device of the present invention not only has structural innovation, but also can automatically perform the work of clamping and screwing the screw cap 12, and in the process of screwing, the local components of the clamp device of the present invention can follow The screwing depth is raised and lowered to improve the smoothness of the screw mounting, so the invention is indeed a novel and practical fixture device which can save labor cost and increase assembly speed.

The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the patent application scope and patent specification content of the present invention, All remain within the scope of the invention patent.
